Optical clocks have reached such an impressive accuracy and stability that the future redefinition of the second will be probably based on an optical transition. Consequently, building time scales based on optical clocks has become a key problem. Unf

Proceedings of the 52nd Annual Precise Time and Time Interval Systems and Applications Meeting.
TWSTFT has been one of the most popular techniques used for comparison of remote atomic clocks. It typically employs the code-phase of a signal modulated by a pseudorandom noise (PN) code sent and received by microwave link via a geostationary teleco

We present two different approaches to broadcasting information to retrieve the GNSS-to-GNSS time offsets needed by users of multi-GNSS signals. Both approaches rely on the broadcast of a single time offset of each GNSS time versus one common time sc

When observed from the ground, the frequency of the atomic clocks flying on the satellites of a Global Navigation Satellite System is referred to as apparent frequency, because it is observed through the on-board signal generation chain, the propagat

Optical clocks have reached an impressive accuracy, surpassing by orders of magnitude that of microwave clocks, so that the optical transitions on which they are based can be considered as ideal candidates for a possible future redefinition of the se
